Hello!

i've posted this question on quite some forums, since I would like to get wider feedback.

I just bought Acer Aspire V3-772G and since I want it to have a nice and comfort life, I bought Quasar cooling pad with following specs:
- fan: 200x200x20mm
- high speed 800 RPM, low speed 500 RPM
- blows into computer
- link to cooling pad: http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&no=181&type=Notebook%20coolers&typ...

The story is as follow: when I bought laptop, I realised J key was oversensitive, so I took it to service, where they changed keyboard. When I took it out of service, I didn't note anything abnormal. I got home in the evening, put laptop on cooling pad and played some games. Soon after that I saw that metal casing around some keys is bended upwards. I'll take it back to service, but I'm just wondering if there's any chance that cooling pad can create such damage or was it just me that didn't realise that damage to casing when I took it out of service. Since it would be wierd to get it fixed, take it back home, put laptop on cooling pad and get the same issue again.

Here are 2 pictures of the damage:

Damage can be seen around keys E, R, P, Š, Đ where laptop casing is much closer to the edge of keys than at some others (especiall at the top).

Thanks in advance and enjoy,

You certainly have inconsistencies in key height.
I don't own your model so I don't know what keys in your photos can be considered the norm.
T, Z, and U for example appear high in relation to *,  Š, Đ.
I would suspect the replacement keyboard is either distorted or has been poorly fitted. I doubt it is the metal casing.
I would definitely have Acer service take another look - it's not acceptable in my opinion.
As for your cooler, I can't see this having any bearing at all on the problem.

Hello and thanks for reply!

Thing is, it's the casing. I've taken ruler and set it on casing and it defenitly is bended. Keys are consistent, so it's ok I was just wondering if case could be bended by cooling pad, since I was thinking since fan is blowing toward laptop (from below) that somehow you could have some pockets of air inside that would increase over time and somehow inflate casing of laptop next to keys.

Sounds like a sci-fi or do you think tat might be plausable?

Thanks and enjoy,

I do not think that it is caused by air pressure from the cooler. The air would leak out elsewhere before it bulged the 'casing'.   This looks like a mechanical fit problem - the 'casing' is probably a bit too long for the available slot.  You should alert Acer Service to this possibility.

There is a remote possibility that it is a thermal problem.  If the frame where the keyboard sits is metal and shrinks due to excessive cooling it could have the same effect. I cannot conceive that manufacturing tolerances would be so tight as to make this a reality.

Cheers again for reply.

About casing being too low, there wasn't any issue before they replaced the keyboard. There is a possibility they swapped casing again, though they didn't write that down in service report.

About excessive cooling, I would doubt that scenario is plausable since I was constantly monitoring temperature, which was 36-39 degrees in idle mode and 68-72 degrees in full load (played Rift for 3 hours with everything on ultra).

It defenitly is weard. Thing is I'm quite paranoid about it, since it's my first notebook and it's brand new, yet I have more issues with it than benefits x)
